CX2119A Low phase noise Crystal Oscillators

The CX2119A is a low-phase-noise, 10MHz oven-controlled crystal oscillator housed in a standard 36×27mm package. It operates stably in environments ranging from –20°C to +70°C, has an aging rate better than 5E-10/day, and offers excellent near-end and far-end phase noise performance. This product is ideal for use in low-phase-noise phase-locked loop (PLL) local oscillator circuits. When connected to an atomic clock, it significantly improves the system's short-term frequency stability and phase noise performance, while effectively suppressing and eliminating clutter interference from the atomic clock.

CX5228A High stability and low phase noise crystal oscillator

The CX5228A is a highly stable, low-phase-noise oven-controlled crystal oscillator (OCC). It utilizes a high-Q crystal resonator, offering excellent frequency stability and phase-noise performance. Operating in a temperature range of -20°C to +70°C, it features an aging rate better than 3E-10/day and a 1Hz phase noise rating of -126dBc/Hz. It is widely used in communications, navigation, radar, reconnaissance, high-end instruments, and high-end audio systems.

CX8617A High stability and double constant temperature Crystal Oscillators

The CX8617A is a dual constant temperature low phase noise crystal oscillator, with excellent phase noise performance and frequency stability, and has good environmental adaptability, and the nominal index can be obtained in the desktop environment.

CX910 Ultra-high stability and low phase noise crystal oscillator

The CX910 is a four-output, dual-temperature, highly stable crystal oscillator. It utilizes SC-cut high-precision crystals, a customized low-noise oscillation circuit, and a pure copper temperature control system. Its phase noise reaches -126dBc/Hz at 1Hz. Internal independent voltage regulation and separate temperature control effectively reduce interference. A multi-stage linear regulator reduces core power supply noise to the nanovolt level, significantly improving phase noise and short-term stability performance at 10MHz output. It is suitable for radar, electronic countermeasures, aerospace measurement and control, and standard phase noise measurement scenarios.

PLOA260 Analog phase-locked thermostat Crystal Oscillators

PLOA260 is a low noise analog phase-locked oscillator which is based on the standard form factor design of BDSTAR TIME, and integrates 1 high performance thermostatic crystal, 1 digital phase-locked loop and 3 isolation amplifiers, and also can be Customized with 1 low phase noise 5MHz crossover output, 5Hz fixed bandwidth filament, 1Hz phase noise, and 1s fixed degree following standard. While the far end noise is determined by the local low noise crystal oscillator, the PLOA260 can be used to optimize the output noise of the clockkeeping room phase trimmer, and is suitable for connecting to the hydrogen clock set phase trimmer, which improves the phase noise performance while maintaining the hydrogen clock second stability

PLOD260 Digital phase-locked thermostat Crystal Oscillators

The PLOD260 is a high-performance phase-locked crystal oscillator (PLOD260) with three 10MHz outputs and one customizable low-phase-noise 5MHz output in a standard BDSTAR TIME form factor. It integrates a high-performance oven-controlled crystal oscillator (OCR) and a fully digital phase-locked loop (PLL). It supports a 10MHz input and has a bandwidth adjustable from 4MHz to 512MHz via RS-232. It is ideal for optimizing the phase noise and short-term stability of rubidium and cesium clocks.
